Abstract

An optical proximity sensor arrangement comprises a first sensor unit with a first emitter and a first detector and a second sensor unit with a second emitter and/or a second detector. The first detector is configured to detect light being emitted by the first emitter and, if applicable, by the second emitter, and being at least partially reflected. If applicable, the second detector is configured to detect light being emitted by the first emitter and being at least partially reflected. A distance between the first emitter and the first detector is, if applicable, less than a distance between the first detector and the second emitter and, if applicable, less than a distance between the first emitter and the second detector.
